To all whom c't may concern Be it known that I, WILLIAM C. BAUER, a citizen of the United States, residing at Neenah, in the county of Winnebago and State of Wisconsin, have invented a new and useful Paper- Making-Machine Slice, of which the following is a specification.

`My invention consists of forming the slice bars of more than the usual number of sections instead of the usual two pieces for allowing of the vertical adjustment of the several sections, at such a distance above the making wire as the density and iiow of the pulp requires for making an even thickness of paper. To an inexperienced person it would naturally be supposed that if the slices were at a uniform distance above the wire entirely across the machine, that a sheet of paper would be produced of a uniform and even thickness. Such however is not the uniform result as all experienced paper makers know, owing to the variations in the density and flow of the paper pulp stock, and various devices have to be resorted to by the machine tender to produce a sheet of even thickness, such as hanging a sheet of paper over the slice bars and letting it hang down upon the apron side and be drawn under the slice where the paper is running too thick, or sometimes an obstruction is placed between the liow box and slices for changing the direction of the How as the thickness of paper being run off requires. In the paper making machines of a few years ago of a width of six feet more or less, the usual two piece slice bars were sufficient for controlling the thickness of the paper, but with machines of nearly or quite double that width, some other means is required, and' by forming the lslices of an additional number of sections,

facilities are provided for gaging the thickness at numerous points along the slices.

My invention is shown in the accompanying drawing, in which,- 4

Figure 1 is an elevation of a slice bar embodying my invention. Fig. 2 is a plan of the slice as it appears in position across the machine. Fig. 3 is an end elevation thereof. Fig. 4 is a vertical section upon the line a, a, of Fig. 2, and showing two sections secured together. Fig. 5 is a vertical section upon the line b, b, of Fig. 2, as the sections appear 1n looking toward the right.

Similar numerals and letters indicate like parts in the several views.

1, indicates the end section of the slice bar formed of a suitable metal, having the end liange 2, into which the bolt 3 is tapped for securing the slice bar to the deckle frame, (not shown,) and a bracket 4, secured upon the upper edge with bolts 5, and which bracket is provided with the vertical .adjusting screw 6, and jam nut 7. A slot 8, is made through which a bolt 9, can be inserted for clamping two sections together between its nut and head, and a bracket 10, which may be integral with the section 1, and is provided with an adjusting screw 11 and jam nut 12, for adjusting said section vertically, with reference to an adjoining section.

The description thus far describes the construction of the usual slices formed of two sections.

My improvement consists of making the end sections nearly one fourth of the length of the distance between the deckle frames and then inserting three sections la, more or less according to the width of the machine, which are lapped upon each other and upon the two end sections and bolted together in a manner similar to that in'which the two end sections have been lapped and bolted together. Each of the intermediate sections is provided with brackets 10a, adjusting screws 11a and jam nuts 12a, and with a slot 8a and bolt 9a. With these live sections, (more or less,) facilities are provided,jby means of the several short sections, for ad- -justing the slice bar at various points in its cured thereto, composed of more than two sections, each section having/means for oongether side by side between opposite ,"deekle' frames and each section having means for l. its vertical adjustment relative to the making wire.
